FAN FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 402,948, dated May 7,1889.

Application filed Sept mber 24, 1888. Serial No. 286,228. lModel.)

To all whom it may concern:

Be it known that we, GEORGE R. LEIBER- SPERGER and GEORGE W. BAILEY, ofSaegerstown, in the county of Crawford and State of Pennsylvania, haveinvented certain new and useful Improvements in Fans for Rocking-Ohairs; and We do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being hadto the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in fans for rocking-chairs; andit consists in, first, the combination, with a rocking-chair, of a rodwhich supports a platform or table, ashaft which has a weight secured toone side thereof at or near its lower end, and a revolving disk securedto its upper end, an adjustable support, a shaft having a fan attachedto its outer end, and a friction-wheel attached to its inner one;second, the arrangement and combination of parts, all of which will bemore fully described hereinafter.

The object of our invention is to provide a fan which can be attached toa rocking-chair and adjusted into any desired relation thereto, andwhich is made to operate as the chair is rocked byaswinging movement ofaweight which is attached to one side of the shaft.

Figure 1 is a perspective of a fan which embodies our inventioncomplete. Fig. 2 is a detail view of the same.

A represents an ordinary rocking-chair, and B an inclosing box, frame,or chamber, which is secured to one side of the chair by means of thesupporting-pieces O, which are clamped or secured to two of the legs ofthe chair by means of any suitable devices. The ends of these two piecesC pass each other and are secured together by means of a set screw, D,thus adapting the pieces 0 to be made extensive, so that they can beapplied to difierent chairs. The box B is secured to the pieces G bysuitable fastenings, G, as shown in Fig. 2, so that its bottom does notcome in contact with the floor. Rising from the top of this box, whichis provided with a lid, H, so as to give access to its interior, is atelescopic supporting-rod, I, having the table or platform J secured toits upper end. This rod I is made telescopic, so that the plat form Jcan be adjusted in relation to the chair at the will of'the operator.The upper end of the rod is secured to one side of the platform, and itsopposite side is braced in position by means of the rods or braces L.From the top of the box B also extends asuitable brace, N, which has oneend to bear against the side of the rod 1, as shown, so as to supportand brace the parts together.

The bottom of the box B forms a support for the lower end of the shaftO,Which is also made telescopic near its upper end, and which also hassecured to its upper end the horizontal revolving disk P, which issupported just above the table or platform J. Secured to one side of therod 0, near its lower end, is a weight, Q, which, as the chair is rockedback and forth, swings around in a circle and causes the shaft 0 torevolve. After the weight has once been caused by the motion of thechair to swing entirely around, the centrifugal force will keep the rodin constant motion as the chair is rocked, and the rapidity of thismotion can be increased or decreased, according to the rapidity withwhich the chair is rocked.

Pivoted upon the upper end of the shaft 0, and supported in a horizontalposition by the table or platform J, is the adjustable support R, uponwhich are placed the adjustable bearings S T for the fan-shaft U. Thissupport B, being pivoted upon the end of the shaft 0, can be freelymoved around through a portion of a circle, and is held in any desiredposition by means of the notched flange V, which is formed upon thetable or platform, and with which the support R engages. By thus givingthe support a horizontal adjustment the fan W can be adjusted back andforth in relation to the chair at the will of the operator. The shaft 0being made telescopic, the disk can also be raised at the same time thatthe table or platform J is adjusted, and thus adjust the fan verticallyin relation to the person sitting in the chair.

Through the support T is made a slot, X,

and through this slot X the inner end of the fan-shaft U passes, and tothe inner end of this fan-shaft is secured the friction-wheel Y. Inorder to keep this frictional wheel Y always in contact with the disk P,a spiral spring, Z, is attached both to the shaft and to the lower partof the support, and this spring exerts its tension in drawing the innerend of the fan-shaft U downward in the slot X, so that the wheel Y willalways bear with suflicient force against the revolving disk to causethe shaft U to revolve with the disk P.

The support R has its edges turned over so as to form guides, and thetwo supports S T are formed by turning up the two ends of the plate E,which has its edges to project slightly beyond the edges of the supportsS I T and thus catch in the guides formed upon the support R.

Aperson sitting in the chair has only to rock back and forth, and as theshaft 0 is inclined first in one direction and then in the other theweight Q follows the motion of the shaft 0 from its own gravity, andthat movement of the chair is sufficiently great to give the weightsufficient momentum to at once swing entirely around. Then the continuedrocking of the chair will cause the weight to continue swinging aroundin a circle and thus operate the shaft.

Having thus described our invention, we claim 1. The combination, with arocking-chair, of a supporting-rod having a table or plat-- form securedto its upper end, a shaft having a weight secured to one side and havinga friction-disk secured to its upper end, suit able supports, a shaftjournaled in the supports, a fan secured to the outer end of the shaft,and a wheel secured to the inner end of the shaft and operating inconnection with the disk, substantially as shown.

2. The combination, with a rocking-chair, of a vertical shaft connectedthereto,aweight secured to one side of the rod, a fan, and anintermediate mechanism, substantially as described, between the shaftand the fan,whereby as the chair is rocked the shaft is automaticallymade to revolve for the purpose of operating the fan, substantially asset forth.

In testimony whereof we aflix. our signatures in presence of twowitnesses.
